In addition to the general web technobabble covered in Chapter 9 of Website Owner’s Manual, we will look at some more technobabble related to different image used on the web.

• World Wide Web in Plain English
  A short video (2:46) using stop-motion photography and paper cut-outs to explain what makes the World Wide Web work.

• SEO For Photographers Made Easy
  This article is more about search engines than about images, but it does have some good material related to our discussion. I recommend the whole article, but the quiz questions will only come from the first and third sections:

  • How the Search Engines read your website (direct link to section)
  • Optimizing Your Photography Website For SEO (direct link to section)

• Web Graphics For Beginners
  These tutorials provide a good introduction to some of the issues related to images on the web. It’s a little dated (the sizes it lists for common screen resolution are way too low now), but overall it’s still a good set of tutorials:

  • Introduction / Part 1: Raster vs. Vector
  • Part 2: Screen vs. Print
  • Part 3: Scaling and Sizing Graphics

• GIF, PNG, JPG. Which One To Use?
  This article provides some good detail about the three primary image formats used on the web today.

Once you have watched or listened to or read these materials, you will need to take a quiz of ten true-false questions. (These questions will be randomly selected from the questions below. You can retake the quiz up to five times. Don’t stress about getting 100% on these quizzes: if you get 80% or better, you will be ready to proceed to the next activity and I will give you the full 3 points.)

All questions should be prefaced with an understood, “According to the author / speaker …”:

1. T/F? Lee LeFever pretends we are really small in order to explain how the world wide web works.
2. T/F? Lee LeFever describes a web browser as a translator, turning the packets of code traveling from the internet into words and images.
3. T/F? The little packets of code that we receive on the internet come from computers known as mainframes.
4. T/F? Lee LeFever describes “links” as words and images on web pages that we can click to go to another web page.
5. T/F? Search engines use computer programs called “crawlers” that surf the web to index every web page they can.
6. T/F? When a “crawler” visits a site from a search engine, it looks at the images and watches the videos to find keywords.
7. T/F? The main objective for all search engines is to provide their users with the most relevant results possible when they search for whatever they are looking for.
8. T/F? To make your site more search-engine friendly, the most important factor is the sharpness and color in your images.
9. T/F? A “vector image” is one produced by many small dots (pixels).
10. T/F? A “vector image” is one produced by a series of calculated equations.
11. T/F? “Pixelation” occurs when an image made of small dots has too few dots to trick the eye into thinking it has form.

13. T/F? Vector graphics are the most common format used on the web today.
14. T/F? Computer monitors only require 72 dots per inch (dpi) to display a bitmap graphic correctly, while a printed graphic should have at least 200 dpi.

16. T/F? The three most common image formats used on the web today are TIF, BMP, and EPS.

19. T/F? GIF images can have transparency.
20. T/F? JPG images can have transparency.
